Real estate refers to the acquisition of possession, control rental or sale of real estate property as a profit-making activity. However, real estate investment can be broadly defined to comprise the acquisition and sale of all kinds or real estate even if it doesn't include residential real property (also known "rural"). The real estate investment industry is usually considered to be a sub-specialty of real estate Investing, but as part of an overall real estate investment plan, the development of real estate is usually considered a distinct sub-specialty. Real estate investing can be accomplished in a variety of ways that include individual property investment and commercial real estate investments. It could also comprise real estate investing, property rental, property investment, property investment mortgage real estate, and various other forms. The process of investing can involve many different types of leases, purchases, or the sale of real estate property. In all cases the real estate investment process involves the purchase of a piece real estate which will later sell at a profit.
